Progress in Reanalysis: Development, Evaluation and Application

Session ID#: 77084

Session Description:
Reanalysis is a scientific method for producing a physically complete estimation of the past state and variability of geophysical systems. Over the last decade, reanalysis data sets have become a popular tool being used for various purposes in weather- and climate-related sciences. Reanalyses are employed as a basis for applications building on long-term gridded data sets, as "true state" estimates in assessing the fidelity of model simulations, or as a source of information when studying short-term variability and long-term changes of the climate system. Continuous developments of reanalysis systems and the production of new global and regional data sets provide constant improvements of quality. The session therefore invites contributions on new developments, evaluation and intercomparison (especially against independent observations) as well as applications of reanalyses. We welcome contributions from all types of reanalyses, including but not limited to global, regional, atmospheric, ocean, land and coupled reanalysis systems.
